Description

TECHNICAL FIELD

[0001] The present application relates to the field of cosmetic technology, in particular to a composition, a preparation method and application thereof. BACKGROUND

[0002] The health status of hair directly affects its appearance and touch. Hair damage is the cause of dull appearance and rough touch and mechanical damage. Bleaching or dyeing and repeated daily hair care process (including using hot hair dryer to dry hair) can cause hair cuticle to lift and peel, cortex layer to form micro-pores and medulla layer to become porous, which can cause light diffuse reflection and light scattering in the internal structure of hair. These damages not only affect the luster of hair, but also cause the hair to become frizzy and difficult to manage.

[0003] In addition, the health status of scalp also has an important influence on the overall appearance and touch of hair. Excessive secretion of scalp oil can make hair look greasy, heavy, lack of fluffiness and lightness. Therefore, in addition to repairing hair damage, the secretion of scalp oil also needs to be considered to maintain the lightness and fluffiness of hair. Although the existing hair care products can improve the luster of hair and reduce frizz to some extent by repairing hair, the repairing effect on the internal structure of hair is limited, and the influence of external oil secretion on the lightness and fluffiness of hair cannot be considered.

[0004] Therefore, it is of great significance to develop a care composition and its application for improving the luster of hair, reducing frizz and enhancing the strength of hair by repairing the internal structure of hair, and having oil control effect. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a composition which can effectively repair the internal structure of hair, improve the luster of hair, reduce frizz and enhance the tensile resistance of hair, and also regulate the secretion of scalp oil, so as to maintain the health and lightness and fluffiness of hair.

[0006] The present application provides a composition, characterized in that it comprises alpha-hydroxy acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether and oat peptide.

[0007] In one embodiment, the alpha-hydroxy acid comprises at least one of malic acid, citric acid, tartaric acid and lactic acid.

[0008] In one embodiment, the source of oat peptide comprises organic oat.

[0009] In one embodiment, the oat peptide comprises dipeptide and tripeptide, and the molecular weight is less than 1 kDa.

[0010] In one embodiment, the oat peptides include dipeptides and tripeptides obtained by enzymatic hydrolysis of proteins in oats, with a molecular weight of less than 1 kDa.

[0011] In one embodiment, the dipeptide and tripeptide include glutamic acid and aspartic acid.

[0012] In one embodiment, the composition comprises the following raw materials in parts by weight: 10-60 parts of α-hydroxy acid, 0.1-30 parts of ergothioneine, 0.1-50 parts of oat peptide, and 1-60 parts of PEG / PPG-14 / 7 dimethyl ether.

[0013] A second aspect of the present invention also provides a method for preparing a composition, comprising the following steps:

[0014] The α-hydroxy acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether and oat peptide were mixed and stirred evenly to obtain the composition.

[0015] A third aspect of the invention also provides the use of the compositions described above or the compositions prepared by the methods described above in cosmetics.

[0016] In addition, the present invention also provides a cosmetic comprising the composition as described above, or the composition obtained by the preparation method described above.

[0017] In one embodiment, the composition is added to the cosmetic in an amount of 0.1-20 wt%.

[0018] In one embodiment, the composition is added to the cosmetic at an amount of 0.1-15 wt%.

[0019] In one embodiment, the cosmetic product includes: shampoo, hair cream, hair oil, or hair liquid.

[0020] In the composition provided by this invention, the α-hydroxy acid is a carboxylic acid with an alcohol functional group at the α-position, which can penetrate into the hair fiber and chelate Ca under the action of a solvent. 2+ It fills the cavity, thereby inhibiting scattering and improving hair shine; the COOH of α-hydroxy acid can form strong and stable hydrogen bonds with the NH of hair protein, preventing water penetration, maintaining hair shape and reducing frizz; at the same time, α-hydroxy acid can promote the renewal of the stratum corneum, remove accumulated dead skin cells and oil clogging pores, thereby achieving an oil control effect.

[0021] Ergothioneine has antioxidant properties, which can protect mitochondria and other organelles in cells from oxidative damage; it also has anti-irritant properties, which can reduce the production of inflammatory factors, thereby reducing the irritation of organic acids to the scalp.

[0022] PEG / PPG-14 / 7 dimethyl ether is a multifunctional organic compound with excellent solubility and penetration-enhancing properties. Its chemical structure allows it to effectively reduce the keratin barrier of the scalp and hair, thereby improving the penetration efficiency of active ingredients. Furthermore, PEG / PPG-14 / 7 dimethyl ether has passed multiple toxicological tests, ensuring both product stability and safety.

[0023] Oat peptides are polypeptides composed of dipeptides and tripeptides with a molecular weight of less than 1 kDa. Due to their low molecular weight and high polarity, oat peptides can penetrate into the hair shaft and enter the cortex, repairing the integrity of hair proteins and enhancing hair elasticity and strength.

[0024] This invention combines α-hydroxy acids, ergothioneine, PEG / PPG-14 / 7 dimethyl ether, and oat peptides, and adjusts their dosage to achieve a synergistic effect. This allows α-hydroxy acids and oat peptides to efficiently penetrate hair fibers, fill hair gaps, enhance the strength of hydrogen bonds in the internal structure of hair, and repair the integrity of hair proteins. This inhibits light scattering, improves hair shine, reduces frizz, and increases hair tensile strength. At the same time, it reduces the irritation of α-hydroxy acids to the scalp and regulates scalp sebum secretion to maintain the volume and lightness of hair. The above-mentioned combination helps to enhance the repair effect of α-hydroxy acids and oat peptides on the internal structure of hair, while regulating scalp sebum secretion and strengthening the scalp barrier function.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention has a composition that repairs hair and controls scalp oil, comprising α-hydroxy acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether and oat peptide. The components work synergistically to not only improve the mildness of the composition, but also significantly enhance the effectiveness of the active ingredients in penetrating the hair and scalp to exert their repairing and oil-controlling effects.

[0027] 2. Through extensive experiments, this invention optimizes the ratio of α-hydroxy acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether, and oat peptides to achieve the best results in hair care.

[0028] 3. The α-hydroxy acid, ergothioneine and oat peptides used in this invention are naturally derived ingredients, which have the advantages of being environmentally friendly and sustainable, and meet the modern consumer's pursuit of green and environmentally friendly products.

[0101] Product effects:

[0102] 1. Human patch test

[0103] Test substances: Shampoos from Examples 1-5 and Comparative Examples 1-9 of this invention;

[0104] Participants: A total of 33 participants, including 15 males and 18 females, aged 20-55 years, who met the criteria for voluntary participation.

[0105] Experimental method: A closed-loop test method was used. The test substance was placed in a suitable patch applicator and applied to the back of the subject with hypoallergenic adhesive tape. The patch was then gently pressed with the palm of the hand to ensure even application to the skin for 24 hours. The blank control group was distilled water.

[0106] Results: The test apparatus was removed after 24 hours, and skin reactions were observed and recorded at 0.5h, 24h, and 48h. The severity of adverse skin reactions is shown in Table 4, and the test results are shown in Table 5.

[0107] Table 4. Grading Criteria for Skin Reactions in Closed Patch Tests

[0108]

[0109] Table 5 Results of human skin patch test

[0110]

[0111]

[0112] The results showed that, among the 33 subjects, no adverse skin reactions occurred with Application Examples 1, 2, 3, 4, 5, 1, 2, 5, and 9; however, varying degrees of adverse skin reactions occurred with Application Examples 3, 4, 6, 7, and 8. These results demonstrate that the shampoos of Application Examples 1-5 of this invention are safe and non-irritating, and gentle on the skin.

[0113] Compared with Comparative Examples 2-5, Application Example 2 did not contain malic acid, Application Example 3 did not contain ergothioneine, Application Example 4 did not contain PEG / PPG-14 / 7 dimethyl ether, and Application Example 5 did not contain oat peptides. Application Examples 3 and 4 showed adverse skin reactions. Compared with Comparative Examples 6-9, Application Example 2 replaced malic acid with salicylic acid in Application Example 6, ergothioneine with dipotassium glycyrrhizate in Application Example 7, PEG / PPG-14 / 7 dimethyl ether with butylene glycol in Application Example 8, and oat peptides with silk peptides in Application Example 9. All Comparative Examples 6-8 showed adverse skin reactions. These results indicate that the compositions of the present invention have a synergistic effect, can reduce the irritation of α-hydroxy acids, and the absence of any component leads to a decrease in efficacy.

[0114] 2. Hair shine test

[0115] Test samples: Shampoos used in Examples 1-5 of this invention, shampoos used in Comparative Examples 1-9, and commercially available shampoos.

[0116] The ingredients of commercially available shampoos are: water, sodium lauryl ether sulfate, disodium cocoamphodiacetate, menthol, panthenol, polyquaternium-10, hydrolyzed keratin, sodium chloride, citric acid, sodium benzoate, (daily) fragrance, sodium hydroxide, and propylene glycol.

[0117] Test Method: A skin gloss test probe was used to test the gloss of hair strands. Hair strands were grouped according to the corresponding data. An appropriate amount of sample was applied to each hair strand, evenly distributed on both sides, and rubbed to create foam. During rubbing, avoid folding or twisting the hair strands to prevent tangling. The foam was then rinsed off with warm water, and the hair was allowed to air dry naturally in a constant temperature and humidity environment. This process was repeated ten times. The gloss of the hair before and immediately after applying the sample was measured, and the percentage increase in gloss after sample application was calculated.

[0118] The test results are shown in Table 6:

[0119] Table 6

[0120]

[0121]

[0122] As shown in Table 6, the hair shine test results indicate that the shampoos prepared in Examples 1-5 significantly improved the percentage of shine compared to commercially available shampoos and Comparative Examples 1-9.

[0123] Compared with Application Example 2, Comparative Examples 1-5 all showed a decrease in shine when any one or more of the raw materials malic acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether, and oat peptides were missing. This indicates that the composition obtained by the present invention through reasonable combination has a synergistic effect, effectively repairing hair and improving its shine.

[0124] Compared with Comparative Examples 6-9 and Application Example 2, when the raw materials malic acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether and oat peptide were replaced with raw materials with similar functions, the shine effect of all of them decreased. This indicates that after the components of the composition of the present invention are replaced, they will not be able to achieve the effect of repairing hair.

[0125] 3. Test of resistance to stretching or breaking

[0126] Test samples: Shampoos from Examples 1-9 and Comparative Examples 1-9 of this invention.

[0127] Test Method: At least 50 hairs were taken from the same damaged hair bundle and divided into 6 groups (experimental group and control group). The samples were weighed (sample volume was 20% of the hair bundle weight), washed, and air-dried. The samples were used twice daily for two consecutive days. On the third day, a single hair tensile test was performed to measure the force generated when the hair broke. Each group effectively broke 50 hairs. The average values ​​of the data from the experimental group and the control group were calculated to obtain T1 and T0. The experimental group used a 5g / L sodium dodecyl sulfate solution before using the samples, while the negative control group also used a 5g / L sodium dodecyl sulfate solution. The rate of change of load at breakage was then calculated.

[0128] The test results are shown in Table 7:

[0129] Table 7. Results of in vitro stretching tests on single hair stalks of real hair.

[0130]

[0131]

[0132] As shown in Table 7, compared with Comparative Examples 1-9, the shampoos in Application Examples 1-9 all showed a significant improvement in their resistance to stretching.

[0133] Comparing Comparative Examples 1-5 with Application Example 2, it can be seen that when any one of the malic acid, ergothioneine, PEG / PPG-14 / 7 dimethyl ether and oat peptides is missing, or all of them are missing, the tensile strength of the composition decreases.

[0134] Comparing Comparative Examples 6-9 with Comparative Example 2, it can be seen that when malic acid was replaced with salicylic acid in Comparative Example 6, ergothioneine was replaced with dipotassium glycyrrhizate in Comparative Example 7, PEG / PPG-14 / 7 dimethyl ether was replaced with butanediol in Comparative Example 8, and oat peptides were replaced with silk protein peptides in Comparative Example 9, their tensile strength decreased. This indicates that after replacing the components of the present invention, a good tensile strength effect cannot be achieved.

[0135] The above results demonstrate that the composition of the present invention has a synergistic effect and can better achieve the effect of tensile strength and toughness.

[0136] 4. Hair strand anti-frizz test

[0137] Test samples: Shampoo samples provided in Application Example 2 and Application Comparative Example 1.

[0138] Test method: Weigh (sample amount is 20% of the weight of the hair bundle), wash the hair bundle, and air dry it naturally under constant temperature and humidity conditions of (25±2)℃ and 50%±5%. Then place it in an environment with a humidity of about 80% (simulating rainy days) and take pictures at 0 and 4 hours respectively. By comparing the degree of curvature and frizz of the hair bundle under high humidity environment and the change in hair bundle volume, the immediate anti-frizz ability of the product can be obtained.

[0139] In high humidity environments, moisture easily penetrates the hair, causing it to swell and become frizzy and curly. An anti-frizz test was conducted on randomly selected application examples 2 and a comparative application example, and the results are as follows: Figure 1 and Figure 2 As shown, hair strands treated with Comparative Example 1 (without the composition) exhibited significant curling, frizz, and increased volume after being placed in a high-humidity environment (80% relative humidity) for 4 hours. In contrast, hair treated with Example 2 remained relatively straight after being placed in a high-humidity environment, without noticeable frizz or curling. This result indicates that the composition of the present invention has a significant immediate anti-frizz effect when applied to shampoo, effectively improving hair manageability in high-humidity environments.

[0140] 5. Scalp oil control test

[0141] Test substances: Shampoos from Examples 1-9 and Comparative Examples 1-9 of this invention;

[0142] Participants: A total of 54 participants, including 26 males and 28 females, aged 20-55 years, who met the criteria for voluntary participation.

[0143] Experimental Method: Subjects did not wash their hair the day before. After waiting 20 minutes at a temperature of 21±1℃ and humidity of 50±10%, scalp oil levels were measured at three points approximately 3cm, 4cm, and 5cm above the hairline. The average of the three measurements had to be ≥100μg / cm². 2 Only after initial testing can samples be screened for inclusion in the group. After the initial value test, the samples are taken home for use, based on a shampooing frequency of once every two days. A follow-up visit is conducted after four weeks of use. The day before the follow-up visit, the hair is not washed. Under conditions of 21±1℃ and 50±10% humidity, the scalp oil content is measured for 20 minutes at three locations approximately 3cm, 4cm, and 5cm above the hairline. This is used to evaluate the sample's oil-controlling effect on the scalp.

[0144] The test results are shown in Table 8:

[0145] Table 8. Analysis of Test Results

[0146]

[0147]

[0148] As shown in Table 8, the shampoos prepared using Examples 1-9 significantly reduced scalp oil content by more than 10.5% after 4 weeks of use. In particular, the scalp oil content of Example 9 was significantly reduced by 20.71%. The shampoos without the composition (using Comparative Example 1) or with a reduced component (using Comparative Examples 2-5) could not achieve the same effect as those using Examples 1-9.

[0149] Comparing Comparative Examples 6-9 with Application Example 2, it can be seen that when the composition is replaced with a component with a similar effect, its oil control ability decreases, indicating that the composition cannot achieve a good oil control effect after the components are replaced.

[0150] In summary, the composition and cosmetics containing the present invention provide outstanding effects in repairing hair, repairing hair core voids, enhancing hair shine, strengthening hydrogen bonds in the internal structure of hair strands, reducing frizz, maintaining hair shape, repairing hair protein integrity, improving hair tensile strength, enhancing hair strength, reducing the irritation of α-hydroxy acids to the skin, enhancing the penetration effect of active ingredients, improving overall care effects, and regulating scalp sebum secretion. This is because the four raw materials in the composition provided by the present invention exert a synergistic effect, effectively improving the repair effect of α-hydroxy acids and oat peptides on the internal structure of hair, regulating scalp sebum secretion, and strengthening the scalp barrier function.
